DARYL RENARD ATKINS v. COMMONWEALTH OF VIRGINIA
Record No. 000395
Supreme Court of Virginia
September 15, 2000
260 Va. 375 | 534 S.E.2d 312
Present: All the Justices
Pаmela A. Rumpz, Assistant Attorney General (Mark L. Earley, Attorney General, on brief), for appellee.
Daryl Renard Atkins was convicted in the Circuit Court of York County of the 1996 capital murder of Eric Michael Nesbitt and sentenced to death. On appeal, we affirmed his conviction, Atkins v. Commonwealth, 257 Va. 160, 180, 510 S.E.2d 445, 457 (1999), but remanded the case to the circuit court for a new penalty proceeding due to an improper jury sentencing verdict form, id. at 177-79, 510 S.E.2d at 456-57.1 At resentencing, a different jury found that there is a probability that Atkins would commit acts of violence in the future
Atkins assigns eight errors on appeal. After considering those issues and conducting our mandated review pursuant to
I. ISSUES REGARDING MITIGATION
In three related assignments of error, Atkins raises the question whether the circuit court improperly inhibited the jury‘s consideration of mitigating evidence. First, he asserts that Virginia‘s bifurcated jury system, as applied when a case is remanded for a new sentencing hearing before a different jury, unconstitutionally limits a defendant‘s ability to present relevant evidence from the guilt phase of the previous trial. Second, Atkins claims that the circuit court erred in limiting his examination of Frederick T. Lyons, an investigator with the York County sheriff‘s officе, thereby denying Atkins the opportunity to present a complete defense, including mitigating evidence, at his new sentencing hearing. Finally, Atkins argues that the circuit court erred in refusing to instruct the jury about mitigating factors. We find no merit to these claims.
Initially, to the extent that Atkins contends that Virginia‘s bifurcated jury system is constitutionally defective because he could not, at his resentencing, present evidence and argue “residual doubt” with regard to his guilt in the commission of the crime, that contention has been previously addressed and rejected by this Court.3 See
However, Atkins contends that the evidence he sought to introduce through the testimony of Lyons was not offered for the purpose of creating “residual doubt” about his guilt. Specifically, during direct examination, Atkins’ counsel asked Lyons, “[A]fter you advised [Atkins] of [his Miranda] rights, did [Atkins] confess to you his involvement in the murder of Eric Nesbitt?” According to Atkins, the information that he sought to elicit by that question was the fact that he had admitted his participation in the murder of Nesbitt. Atkins argues that such information was relevant to the issues of Atkins’ remorse and his cooperation with law enforcement authorities, both of which are proper subjects of mitigating evidence.
The Commonwealth objected to the question, contending that it called for a hearsay statement. The Commonwealth also noted that, while Atkins confessed to Lyons his involvement in the abduction, robbery, and murder of Nesbitt, Atkins denied that he was guilty of capital murder. In the confession to Lyons, Atkins maintained that his accomplice alone was the “triggerman.” Thus, according to the Commonwealth, for Lyons to appropriately answer the propounded question, he would have to tell the jury that Atkins denied that he pulled the trigger, which would have been contrary to the circuit court‘s prior ruling that evidence regarding Atkins’ guilt would not be admitted at the resentencing hearing.
The circuit court sustained the Commonwealth‘s objection on the basis that the testimony being elicited from Lyons was hearsay.5 We agree.
In any event, we believe that the information that Atkins sought to elicit from Lyons improperly would have interjected at the new sentencing hearing a question about Atkins’ guilt. In that statement to Lyons, Atkins denied that he was the “triggerman” and accused his accomplice of shooting Nesbitt. Atkins, 257 Va. at 175, 510 S.E.2d at 455. As we previously stated, a defendant is not allowed to argue or present evidence of “residual doubt” at a new sentencing hearing. Stockton, 241 Va. at 211, 402 S.E.2d at 207.
Finally, Atkins contends that the circuit court erred by denying certain proposed instructions on the mitigation factors contained in
II. ISSUES REGARDING THE JURY
Atkins raises two issues with regard to the composition and selection of the jury. He first contends that the circuit court erred in denying his motion to strike the entire venire because it did not accurately represent thе demographic make-up of the population of York County. Second, he challenges the Commonwealth‘s use of one of its peremptory strikes.
With regard to the first issue, Atkins argued at trial that the venire, which contained only three Black members, did not represent a fair cross-section of the community. According to Atkins’ counsel, York County‘s population is 30 percent Black. In denying Atkins’ motion, the circuit court noted that the venire had been randomly selected.
Systematic exclusion of a “distinctive group in the community” must be shown in order to establish that a defendant‘s constitutional right to a fair jury selection system has been violated. Chichester v. Commonwealth, 248 Va. 311, 324, 448 S.E.2d 638, 647 (1994), cert. denied, 513 U.S. 1166 (1995). Atkins does not contend that there was such exclusion, nor does the record in this case suggest any systematic exclusion of Black members of the community from the venire. Thus, we find no merit in Atkins’ claim.
On the second issue, Atkins сontends that the Commonwealth‘s exercise of a peremptory strike to remove the only remaining Black juror violated the rule established in Batson v. Kentucky, 476 U.S. 79 (1986), holding that peremptory strikes based solely upon a juror‘s race violate the Equal Protection Clause. In deciding whether a peremptory strike is racially motivated in violation of Batson, a trial court “must consider the basis of the challenge[], the reasons proffered for the strike[], and any argument presented that such reasons, even if race-neutral, are pretextual, to determine whether the challenger has met [the] burden of proving purposeful
The juror in question testified that he took medication for a thyroid condition and that the medication caused him to feel “bombed out” and “drowsy” at times. Because of the juror‘s medical condition, the Commonwealth expressed concern about the juror‘s ability to pay close attention to the evidence. The circuit court determined that the Commonwealth had proffered a sufficiently race-neutral reason to strike the juror, and we conclude that this finding was not clearly erroneous. See Stockton, 241 Va. at 209, 402 S.E.2d. at 205-206 (concern about juror‘s attentiveness was race-neutral reason for striking juror).
III. MOTION TO STRIKE COMMONWEALTH‘S EVIDENCE
Next, Atkins asserts that the circuit court should have granted his motion to strike the Commonwealth‘s evidence at the new sentencing hearing because that evidence was insufficient to prove either the future dangerousness or the vileness aggravating factor. Atkins makes no argument on this аssignment of error beyond this mere assertion. Upon reviewing the record, we find evidence sufficient to prove beyond a reasonable doubt both Atkins’ future dangerousness and the vileness of his crime.
To establish the future dangerousness predicate for imposition of the death penalty, the factfinder may consider a defendant‘s past criminal record, a defendant‘s prior history, the circumstances surrounding the commission of the offense under consideration, and the heinousness of the crime. Edmonds v. Commonwealth, 229 Va. 303, 312, 329 S.E.2d 807, 813, cert. denied, 474 U.S. 975 (1985). In the present case, the Commonwealth presented evidence showing that Atkins had at least 18 prior felony convictions for such crimes as attempted robbery, robbery, abduction, breaking and entering with the intent to commit larceny, grand larceny, maiming, and use of a firearm. In addition, the jury not only heard the details of several robberies that Atkins сommitted, including one in which Atkins hit a victim over the head with a bottle, but also learned about an incident during which he shot a woman in the stomach without provocation.
With respect to the vileness predicate,
Based on testimony from the assistant chief medical examiner who autopsied Nesbitt‘s body, the jury learned that Atkins shot Nesbitt eight times. Three of the gunshots caused mortal wounds. One of those gunshots penetrated the left chest cavity and perforated both lungs and the heart; the second one, to the left lateral back, perforated the right lung and aorta; and the third fatal shot perforated the arm, re-entered the abdomen, and perforated the iliac artery. However, none of the fatal shots was immediately lethal; they would not have caused immediate unconsciousness or paralysis; and Nesbitt may have survived several minutes before dying from internal bleeding. Nesbitt also sustained several scrapes or abrasions, including a large linear abrasion on his right forehead.
This Court has defined the term “aggravated battery” used in
IV. PREJUDICE AND PROPORTIONALITY REVIEW
Whenever a sentence of death is imposed, this Court is required to determine whether that sentеnce “was imposed under the influence of passion, prejudice or any other arbitrary factor; and [w]hether the sentence of death is excessive or disproportionate to the penalty imposed in similar cases, considering both the crime and the defendant.”
With respect to the proportionality question, Atkins does not argue that his death sentence is disproportionate to the penalties imposed for crimes similar to the one he perpetrated, namely premeditated murder with a firearm in the commission of a robbery, where thе death penalty was imposed on the basis of both the future dangerousness and vileness predicates. Nor, given our previous cases, could he do so convincingly because juries in this Commonwealth regularly impose the death penalty for capital murders comparable to the one at issue in this case.7 See Graham v. Commonwealth, 250 Va. 79, 83, 459 S.E.2d 97, 98-99, cert. denied, 516 U.S. 997 (1995) (death sentence imposed for murder in commission of robbery based on both vileness and future dangerousness predicates; defendant had 14 prior convictions; victim shot while lying in parking lot); Strickler v. Commonwealth, 241 Va. 482, 496-98, 404 S.E.2d 227, 236-37, cert. denied, 502 U.S. 944 (1991) (death sentence imposed upon findings of vileness and future dangerousness where defendant with eight felony convictions took victim to deserted field and killed her; death was not instantaneous); Gray, 233 Va. at 341, 352-54, 356 S.E.2d at 172-73, 179-80 (defendant with at least 13 prior felony convictions sentenced to die based on future dangerousness and vileness after forcing victim into his car, taking victim‘s wallet and robbing victim‘s store, and then driving to secluded area where defendant shot victim six times after assuring victim that he would not be harmed); Edmonds, 229 Va. at 304, 307, 312-14, 329 S.E.2d at 809-10, 813-15 (during robbery, victim sustained multiple wounds including stab wound to neck; defendant had 3 felony and 13 misdemeanor convictions; death sentence imposed based on findings of vileness and future dangerousness); Briley v. Commonwealth, 221 Va. 563, 566-68, 578, 580-81, 273 S.E.2d 57, 58-60, 66-68 (1980) (defendant convicted of capital murder in commission of robbery and sentenced to death based on findings of vileness and future dangerousness; victim forced to lie on floor during rape of victim‘s mother and murder of both parents prior
Focusing on the statutory directive that this Court‘s proportionality review take into account not only the crime but also the defendant, see
Atkins’ full scale IQ score was based on a test known as the Wechsler Adult Intelligence Scale-III (WAIS-III), which was administered to him by a forensic clinical psychologist, Dr. Evan Stuart Nelson.8 According to Dr. Nelson, Atkins’ full scale IQ of 59 means that Atkins is mildly mentally retarded. See American Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) 40 (1994). However, Dr. Nelson also acknowledged that Atkins might have scored two or three points higher if he had not been mildly depressed when Dr. Nelson administered the test.
Dr. Nelson further explained that a diagnosis of mental retardation is not simply a question of an IQ score. Mental retardation also involves the inability to function independently as compared to the norm for persons of the same age. Consequently, a diagnosis of mental retardation is based on an individual‘s IQ scores along with that person‘s ability to function in the world. Finally, despite his opinion that Atkins is mildly mentally retarded, Dr. Nelson admitted that Atkins’ capacity to appreciate the criminal nature of his conduct was impaired, but not destroyed; that Atkins understood that it was wrong to shoot Nesbitt; and that Atkins meеts the general criteria for the diagnosis of an antisocial personality disorder.
In addition to Dr. Nelson‘s testimony, the jury heard testimony from Dr. Stanton E. Samenow, a forensic clinical psychologist called
Dr. Samenow also reviewed Atkins’ academic records and noted that, while Atkins had passed the Literacy Passport Test, his academic performance had been terrible and that his school records were “punctuated with statements” by teachers about Atkins’ lack of motivation and concentration, his poor study habits, and his ability to do better in school. Finally, Dr. Samenow, like Dr. Nelson, opined that Atkins was able to appreciate the criminality of his conduct and to conform his behavior to the requirements of the law, and that Atkins satisfies most of the criteria for the diagnosis of an antisocial personality disorder.
The Supreme Court of the United States has ruled that imposition of the death рenalty on a mentally retarded defendant with the approximate reasoning capacity of a seven-year-old child does not violate the Eighth Amendment prohibition against cruel and unusual punishment solely because of the defendant‘s mental retardation. Penry, 492 U.S. at 336, 340. In that case, the Court recognized that the abilities and experiences of mentally retarded individuals vary. Thus, the Court was unwilling to conclude that all mentally retarded people, “by virtue of their mental retardation alone, and apart from any individualized consideration of their personal responsibility[,] inevitably lack the cognitive, volitional, and moral capacity to act with the degree of culpability associated with the death penalty.” Id. at 338. The Court also refused to rely on the concept of “mental age,” noting that it is problematic in several respects and thаt courts have generally been reluctant to use it as a basis for excusing a defendant from criminal responsibility. Id. at 339. However, the Court did state that a “sentencing body must be allowed to consider
In Virginia, the mental retardation of a defendant is one of the factors that may be considered in mitigation of capital murder.
In conducting the mandated proportionality review and examining the records accumulated pursuant to
With regard to the issue of adaptive functioning, Dr. Nelson testified that, in determining an individual‘s ability to function independently, it was necessary to talk with family members, and to review school and employment records. He further stated that he had followed through on that inquiry by reviewing Atkins’ academic records and talking to Atkins’ parents. As a result of the inquiry, Dr. Nelson reported that Atkins had received poor grades, failed many tests and classes, and was placed in remedial academic courses on a number of occаsions. He also stated that Atkins’ parents described a number of deficits, but Dr. Nelson never elaborated on the nature of those deficits. In other words, Dr. Nelson never identified an area of significant limitation in Atkins’ adaptive functioning other than what he termed Atkins’ “academic failure.”11
In contrast, Dr. Samenow provided the following explanation when asked whether Atkins has any impairment in his adaptive functioning:
Well, Mr. Atkins never lived independently. In other words, he was not a self-supporting member of society. However, he told me he was able to wash his clothes, wash and dry his clothes, he used his parents’ washing machine and dryer. He told me - when I asked him if he was able to cook, he gave me his recipe for cooking chicken.
This Defendant, ... as I understand it, lived a life in which he didn‘t work, and I don‘t mean just didn‘t hold a job, that he didn‘t do, but then again there are a lot of 18-year-olds who maybe haven‘t worked because they‘ve been in school. But he didn‘t work in school either.
Thus, considering “both the crime and the defendant,”
Accordingly, we perceive no reason to commute Atkins’ sentence of death and will affirm the judgment of the circuit court.
Affirmed.
JUSTICE HASSELL, with whom JUSTICE KOONTZ joins, concurring in part and dissenting in part.

II.
Dr. Evan S. Nelson qualified as an expert witness on the subjects of clinical and forensic psychology. He testified on behalf of the defendant, Daryl Renard Atkins. Dr. Nelson rеviewed the defendant‘s school records, psychological test data, and certain information related to the defendant‘s capital murder conviction and his prior convictions. Dr. Nelson also interviewed members of the defendant‘s family.
“There are a number of IQ tests on the market. Some of them are for special niches of population. But the WAIS is one of the two that is recognized throughout the United States as a standard for assessing intelligence.
“It‘s the one that‘s most frequently cited, for example, in state laws for identifying who qualifies for a learning disability or a mental retardation, the one that‘s most often cited in Federal disability laws for making determinations involving an IQ or neurologic deficits.”
According to Dr. Nelson, there are 13 major subsections of the test that he administered to the defendant. Dr. Nelson administered all 13 of the major subsections to the defendant and determined that the defendant had a full-scale IQ of 59. Dr. Nelson observed:
“Mental retardation is about two things. Number one, it‘s about an IQ of around 70 or below, and there [is] some space there, 70 or plus or minus five points is the official criteria....
“Secondly, adaptive behavior. Being mentally retarded isn‘t just a low score on this test. It‘s about lacking certain abilities to function independently compared to what you‘d expect for other persons your age. That‘s a really important criteri[on]. Because there are some people who can score really well or really poorly on this test but who either do or don‘t function well in society. So you have to go out and find out by talking with family members and school records and employment records, if they have any, about how they function in the world at large. You need the two of them together to be able to say someone is mentally retarded.”
Dr. Nelson, who is a specialist in the assessment of mental illnesses, opined that the defendant was mentally retarded based upon his IQ score of 59 and his limited capacity for adaptive behavior. Dr. Nelson pointed out that in addition to the defendant‘s low IQ score of 59, the defendant‘s public school academic records “are crystal clear that he has been an academic failure since the very beginning.” Dr. Nelson testified that the “lack of variation” in the defendant‘s
Even though the defendant was not classified as mentally retarded when he was a student in the Hampton Public Schools Division, his academic performance was very poor. He scored below the 20th percentile in almost every standardized test he took. He failed the second and tenth grades. He was socially advanced from the fourth grade to the fifth grade.
When the defendant was an eighth-grade student, he received failing grades in all his classes, and he scored in the 15th percentile of standardized achievement tests. When he was a tenth-grade student, he scored in the 6th percentile. The defendant, when a student in high school, was placed in lower-level classes for slow learners and classes with intensive instruction for remedial deficits. His grade point average in high school was 1.26 out of a possible 4.0. The defendant did not graduate from high sсhool.
Dr. Stanton E. Samenow qualified as an expert witness in the subjects of clinical psychology and forensic psychology. He testified on behalf of the Commonwealth. Dr. Samenow interviewed the defendant twice. Dr. Samenow did not administer an IQ test to the defendant. Rather, he asked the defendant some questions.
Dr. Samenow testified that the defendant was able to relate to him certain recent events and historical facts. For example, the defendant knew the name of the Governor of Virginia and knew that former President John F. Kennedy‘s son had died in an airplane accident. The defendant was also able to associate certain words and to tell a story utilizing certain pictures. Dr. Samenow did not give the defendant a complete intelligence test, but essentially picked and chose certain questions from various tests to query the defendant.
For example, during cross-examination, Dr. Samenow testified:
“As I indicated... I gave portions of the Wechsler Memory Scale, the selected items of the Wechsler Adult Intelligence Scale, namely, from similarities, vocabulary and comprehension, and I also gave the Thematic Apperception Test, which in itself is not an intelligence test but it certainly does give some indication of a person‘s use of syntax, language, vocabulary, and these were portions. I want to underscore, and I said this yesterday, portions of those tests.”
“Q: In your interviews with the Defendant, did you ascertain any evidence suggestive of mental retardation?
“A: I found absolutely no evidence other than the IQ score that I knew of, because I reviewed a number of materials. No evidence did I find other than that indicating that the Defendant was in the least bit mentally retarded.
“Q: Do you have an expert opinion as to the Defendant‘s intellect?
“A: He is of average intelligence, at least.
“Q: Explain the basis of how you came to this conclusion.
“A: Largely though several indices. One is the vocabulary and syntax that he used in talking with me. And I have many examples.”
Significantly, Dr. Samenow testified that Dr. Nelson‘s calculations of the scores on the tests administered to the defendant to ascertain the defendant‘s IQ were correct. Dr. Samenow did not conduct a full evaluation of the defendant, nor did he use questions from the most recent test when he examined the defendant.
III.
“Mental retardation refers to substantial limitations in present functioning. It is characterized by significantly subaverage intellectual functioning, existing concurrently with related limitations in two or more of the following applicable adaptive skill areas: Communication, self-care, home living, social skills, community use, self-direction, health and safety, functional academics, leisurе, and work. Mental retardation manifests itself before age 18.”
Carroll J. Jones, An Introduction to the Nature and Needs of Students with Mild Disabilities: Mild Mental Retardation, Behavior Disorders, and Learning Disabilities, 39 (1996).
Persons with an IQ level in the range of 50 through 55 to 70 are classified as having mild mental retardation. The following table of diagnostic criteria for mental retardation appears in Kaplan & Sadock‘s Comprehensive Textbook of Psychiatry 2598, Benjamin J. Sadock & Virginia A. Sadock eds., (7th ed. 2000):
| “Mental Retardation | IQ range | Mental age (years) |
| Mild | 50-69 | 9 to under 12 |
| Moderate | 35-49 | 6 to under 9 |
| Severe | 20-34 | 3 to under 6 |
| Profound | Below 20 | Less than 3” |
According to Doctors Kaplan & Sadock:
“Mild mental retardation (I.Q., 55 to 70) characterizes the largest group of persons with mental retardation, possibly as many as 85 percent of the total. These individuals appear similar to nonretarded individuals and often blend into the general population in the years before and after formal schooling. Many achieve academic skills at the sixth grade level or higher, and some graduate from high schoоl. As adults, many of these individuals hold jobs, marry, and raise families — yet at times they may appear slow or need extra help negotiating life‘s problems and tasks.”
Id. The evidence of record shows that the defendant‘s full-scale IQ score of 59 falls within the range considered mild mental retardation. Less than one percent of the American population at large has a score of 59 or below.
I would commute the defendant‘s sentence of death to life imprisonment without the possibility of parole because I believe that the sentence of death is “excessive... to the penalty imposed in similar cases, considering both the crime and the defendant.” Upon my independent review of the entire record in this case, see Vinson v. Commonwealth, 258 Va. 459, 472, 522 S.E.2d 170, 179 (1999), cert. denied, 530 U.S. 1218, 120 S.Ct. 2226 (2000), it is clear that this defendant is mentally retarded. This defendant, who has an IQ of 59 and a limited capacity for adaptive behavior, has the cognitive ability or mental age of a child between 9 and 12 years of age. This Court has never approved of the imposition of the death penalty upon a defendant who is mentally retarded and has an IQ as low as 59.
I simply place no credence whatsoever in Dr. Samenow‘s opinion that the defendant possesses at least average intelligence. I would hold that Dr. Samenow‘s opinion that the defendant possesses average intelligence is incredulous as a matter of law. Indeed, I am perplexed that Dr. Samenow, who did not administer a complete IQ test to the defendant and admittedly asked the defendant questions based upon bits and pieces of outdated tests to supposedly evaluate the
Dr. Samenow admitted that he does not contest the manner in which Dr. Nelson computed the defendant‘s IQ scores. Additionally, Dr. Samenow admitted that some of the questions he administered to the defendant were based upon a test developed in 1939. Dr. Samenow described this test as “[a]n old standard,” yet, he used this obsolete test even though he acknowledged that the Ethical Principles of Psychologists and Code of Conduct, Ethical Standards 2.07 (1992) of the American Psychological Association, prohibits the use of obsolete tests and outdated test results and specifically states that “psychologists do not base such decisions or recommendations on tests and measures that are obsolete and not useful for the current purpose.”
Moreover, according to the testimony and medical literature, an assessment of mental retardation is predicated upon the subject‘s IQ score and the subject‘s adaptive behavior. Dr. Samenow, however, could not validly opine about the defendant‘s adaptive behavior because he had not interviewed anyone who had observed the defendant prior to his incarceration. Additionally, Dr. Samenow‘s methodology is flawed because when he improperly administered portions of certain tests, he failed to comply with the relevant instructions for those tests.
Also, I place no credence in Dr. Samenow‘s opinion that the defendant possesses an average intelligence because of the defendant‘s vocabulary and his ability to relate certain historical facts to Dr. Samenow. It is common knowledge that many children as young as eight years old are capable of relating the same historical facts that the defendant described and possess a vocabulary similar to the defendant‘s vocabulary.
I recognize that the United States Supreme Court has held that the imposition of the death penalty upon mentally retarded criminal defendants does not violate the Eighth Amendment to the United States Constitution. See Penry v. Lynaugh, 492 U.S. 302, 340 (1989). However, the issue in this appeal is not whether the imposition of capital punishment upon a mentally retarded criminal defendant violates the federal Constitution. Rather, the issue in this appeal is whether under
IV.
I recognize that this defendant has a history of violent criminal behavior. I also recognize that this defendant is clearly a significant danger to society. Therefore, I would commute this defendant‘s sentence to life imprisonment without the possibility of parole.
JUSTICE KOONTZ, with whom JUSTICE HASSELL joins, dissenting.
I agree with the view expressed in detail in Justice Hassell‘s dissent in this case. For the reasons expressed therein and for the following reasons, I would also commute Daryl Renard Atkins’ death sentence to imprisonment for life without the possibility of parole.
Justice Hassell correctly observes that “[t]his Court has never approved the imposition of the death penalty upon a defendant who is mentally retarded and has an IQ as low as 59.” In footnote 9, the majority refers to Mackall v. Commonwealth, 236 Va. 240, 372 S.E.2d 759, 769 (1988), to note that this Court has upheld, however, a sentence of death for а defendant with an IQ of 64 who was convicted of capital murder committed during a robbery. In another part of its opinion, the majority further correctly notes that “Dr. Nelson also acknowledged that Atkins might have scored two or three points higher if he had not been mildly depressed when Dr. Nelson administered the [IQ] test.” In doing so, apparently the majority suggests that there is no significant distinction between Atkins’ full scale IQ and that of Mackall. In my view, our statutory mandate under
